Before I introduce the work, let me tell you a little about the bigger picture story.

When the Sydney bus picture looks like this, we look to unique methods of understanding and solving the problems. High quality interchanges with consistent wayfinding and signage • Address bus pinch points with missing link bus priority treatments on: – Pittwater Road north of, and across, Narrabeen Lakes – Pittwater Road between Dee Why and Brookvale – Military Road between The Spit and Neutral Bay In the longer term: • Complete investigation of Bus Rapid Transit for the Northern Beaches • New off-street bus interchange facility north west of Manly • New bus interchange facility at Neutral Bay Junction

Story of how we got to this position

Story of how we got to this position

One of our latest Bus priority projects was the Northern Beaches corridor from Neutral Bay to Mona Vale. This was a broader study of the overall performance of the corridor and bus prioritisation options. It involved an extensive analysis of PTIPs, GPS and travel time data. This corridor is notoriously congested, as it is the primary mode of transport for people travelling to from and within the Northern Beaches area of Sydney. In addition to this, Neutral Bay forms a funnel for many of the trips travelling to and from parts of Sydney south of the harbour, including the CBD.

We analysed over 820,000 bus trips averaged over a month in 2015. the objective was to identify the all of the pinchpoints, speed, variability and travel times along the corridor, in order to prioritise investment into bus infrastructure. Ultimately there were expected to be trade-offs in the competition for road space along this corridor.

Step by step process Automated data cleansing Metrics agreed with client – based on the amended performance standards set within Sydney’s Bus Future. Metrics are average travel speed and variability – variability is… E.g. Average speeds between 18-25km/hr and Variability between 24-40%

GEETA – have shortened points on the slide. Time point data analysis Allows finer-grained view of corridor data, identification of specific problem locations Creates a larger volume of data to analyse GIS is an effective application to process and analyse large volume of data. Method: First steps involved processing raw PTIPs data into a format for analysis and excluding irrelevant and erroneous data. The Northern Beaches corridor - 106 sections , ranging between 150 – 170 m.

GEETA – have shortened points on the slide. Time point data analysis The data imported directly into ESRI ArcGIS geodatabase and mapped using x,y coordinates All data points outside 40 m of the road excluded Using linear referencing tool in ArcGIS, northbound and southbound routes were created and each data point had a chainage calculated. This method was used to interpolate travel times and variability for each segment The average travel times and variability was then visualized on a map.

GEETA Describe how this graphic was created and what it shows. Discuss thresholds – e.g. travel speeds and variability upper and lower bounds

Thresholds based on desired performance as discussed in Sydney’s Bus Futures and agreed with Transport for NSW Average Speed ideally above 25km/hr Variability less than 40%

The data analysis study was used as part of broader study on Northern Beaches corridor performance and opportunities investigation Previously this work has fed into business cases for corridor improvements Creating a stream-lined data analysis service for our clients – well tested and proven Opportunities to use method within Auckland and New Zealand transport markets

Who in the room catches to the bus to and from work? Who catches the bus for fun? Or relies on it for

I would not be surprised if your bus journey to work was one of the most frustrating moments in your day. It certainly has been for me. I am actually a train convert.

CUSTOMER PERSPECTIVE
But what happens when Sydney’s roads look like this?

BUS PRIORITY IN SYDNEY
Bus priority story – what do we want?
 Bus network which is reliable, efficiency,
understandable
 NSW Premiere’s target for 90% of peak travel
on road routes is on time
 Partner with NSW Government’s investment
strategy
 Confidence in where to spend
Task: Develop analysis tool for analysing data
and identifying corridor pinchpoints.

7.
Transport for NSW has commissioned several pinch points analysis for improved
bus priority infrastructure, along several corridors.
 Using the Public Transport Information and Priority System (PTIPS)

GEO-SPATIAL ANALYSIS
Time point data analysis
Data imported and mapped using x,y
co-ordinates
 5: Calculated average travel times
for each section, determined by
interpolating the times at which the
bus arrived at the segment ends.
 6: Analysis was visualized on a
map.

NEXT STEPS
 Inputs into broader study on Northern Beaches corridor performance and
opportunities investigation
 Previously this work has fed into business cases for corridor improvements
 Creating a stream-lined data analysis service for our clients – well tested
and proven
 Combine with other tested analysis methods and develop a toolkit for
corridor performance analysis, option development and assessment
 Opportunities to use method within Auckland and New Zealand
comparable transport markets
